I Haven't Even Had Sex with Eun-ji Yet?

My heart pounds. My cock stands stiff and erect, twitching with anticipation. Park Ah-young, completely naked, straddles me and slowly lowers her hips. Her already soaked pussy brushes against my glans with soft taps, hovering right at the edge of penetration. And in the distance, a pair of eyes stare at me—no, at us. Park Eun-ji stands frozen, hand clamped over her mouth.

It's thrilling. Even with her face half-hidden, her irritation is obvious. Her shoulders tremble as she clenches her fists, looking almost pitiful.

"...I'm putting it in. Your cock... inside my pussy... I'm putting it in, okay?"

Park Ah-young seems to enjoy her sister's reaction. She keeps glancing over at Park Eun-ji while speaking. Tap. Tap.

"Ah, why? I was really about to put it in..."

Park Ah-young flinches when she realizes I've noticed her peeking.

"Turn around."

"...Around? Why?"

"Hurry."

"...Like this? Ah..."

Park Ah-young, who had been facing me, turns her body. Her pale back is now pressed against my chest, and her gaze naturally falls on Park Eun-ji.

"Hnn...♥ When Eun-ji's watching, it's so embarrassing... what do I do?"

She meets her sister's eyes for a moment before burying her face against my chest again. Park Eun-ji's glare only grows more intense.

"It's fine."

"I'm not fine though... why do you keep saying it's fine?"

"Or should we just ‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠stop here?"

"...I don't want that."

Even now, it looks like she's putting on an act. The faint smile playing on her lips says it all.

"Noona."

"...Yeah."

"Spread your legs more."

"Ah, seriously... haah, hnn... haaang...♥"

A stream of pussy juice flows out. Park Ah-young is gushing like a faucet, soaking everything below. Squish. Squish. Squish.

"Hnn... ha, haah... hnn, hnn!"

Her inner walls, already glistening, part as my fingers sink in. Her pussy hair, drenched in fluids, clings softly to her skin.

"...You want it inside too, don't you, Noona?"

"Y-yeah... but Eun-ji keeps staring..."

She says it like she's suddenly self-conscious, yet her voice carries a deliberate edge meant for her sister to hear.

"If you don't put it in soon, I'll just do it with Eun-ji instead."

"Ah... that... I don't like that even more..."

She keeps checking her sister's expression. Meanwhile, her pussy keeps twitching hungrily.

"...Then I'll put it in. I'm really going to put it in..."

Park Ah-young adjusts her position. Feet planted firmly on the floor, she lifts her hips. Press.

"Hnn, hnn...♥"

She lets out a small whimper as my glans settles against her entrance.

"Kyaa! Heh, heehee..."

The glans slips, and her ass settles back onto my hips. Her slick juices make everything slippery. She leans back against me, lying down fully.

"...It's too big, it won't go in easily... I'll try again, heehee..."

She gives an embarrassed laugh and starts moving again. Press. Press.

"Haah, ha... hnn...♥ It keeps bouncing around..."

She complains about my cock springing back every time she tries to push down.

"...Stay still... ah, ahhn...♥"

Finally, she lowers one arm for support. Her hand reaches for my cock, guiding it toward her drenched entrance.

"Ha, haah...! I-it's going in... just a little more, hnn, hnn...♥"

Her folds spread. A wet squelch echoes softly. More juices trickle down my shaft and onto my hips. Squelch.

"Hnn, haaah..."

The warm, slick heat envelops my glans. Her walls squeeze, trying to push me back out.

"I-it's going in...!! Just a bit more, come on!"

With her frustrated cry, my cock forces her pussy open again. I want to grab her hips and slam her down, but I hold back.

"Hnn! Ha, haah...!"

"Ah, mm... haah, haaah..."

My head tilts back on its own. Electricity races up my spine.

"Haaang...♥ Just a little more!!"

The thickest part—the glans—finally disappears inside her. All it would take now is a little weight and I'd be buried to the hilt.

"Kyaa, kyaaah...!!"

The warm sensation against my face vanishes. Her smooth skin suddenly pulls away. Park Ah-young tumbles forward onto the floor with a thud.

"Ah..."

My cock, now coated in a thin layer of her juices, twitches in the air, aching.

"...What the hell was that all of a sudden?"

"Th-that was me! I should be the one asking!!"

Park Eun-ji's voice rings out, echoing through the living room.

"Ow... what? Wh-why all of a sudden..."

"Unni! Are you out of your mind?! What the hell do you think you're doing?!"

"...No, I mean, say something... you were just standing there... and then suddenly this?"

Park Ah-young hesitates at her sister's blazing eyes. That glare carries a familiar kind of terror.

"...Could you back off?"

"You... shut your fucking mouth."

Park Eun-ji grits her teeth, shoulders shaking as she fights to stay calm.

‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠

"...Get out. Right now. Put your clothes on and leave."

The sudden order makes Park Ah-young's shoulders tremble. She knows she's come between us, so she stays quiet.

"N-no... but why so suddenly... really, why?"

Instead, Park Ah-young looks genuinely wronged. After all, there hadn't been any objections until now. She had worried whether this was even okay, but her sister had only watched in silence—and even seemed to enjoy it. Being shoved away and told to leave feels like a bolt from the blue.

"...Suddenly? Are you seriously saying 'suddenly' right now?"

"W-well, yeah... you were just standing there, and then all of a sudden— I really don't get it."

Park Ah-young still looks confused. Park Eun-ji stares between me and her sister in disbelief.

"...I-I just thought... it was okay to do it together... You should've said something from the start. Doing this out of nowhere is... weird, you know?"

"Unni... what the hell did that bastard do to you? Snap out of it!"

"Wh-what? What do you mean? It just... happened. Do I have to explain everything?!"

Park Ah-young's voice rises, flustered. Of course she's panicking—she can't exactly tell her sister that she had pulled down my pants, played with my cock, and even sucked it.

"...Let's just go, okay? We can talk this out..."

"Wh-what talk? I-I don't have anything to say..."

"...Still, let's not do this. Let's talk properly. It's okay, right?"

"No... it's not okay... and I really don't have anything to say, okay?"

"Ah, seriously! Then why the hell are you still here?!"

"Wh-why are you yelling? I don't even know why you're acting like this..."

They aren't getting ‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠through to each other. Their goals and what they want to say are completely different—it's only natural.

"...You don't have to do this. That bastard... I can just—"

"No! Let go! Let go of me!"

Park Eun-ji grabs Park Ah-young's wrist and tries to pull her up. Park Ah-young stays glued to the floor, refusing to stand.

"Unni! Get a grip!"

"Ah, what do you want?! Should I go first then?! Fine, you do it first! I'll go after, okay?! So just let go already!"

"Haa... what is this mess..."

Park Eun-ji assumes I'm blackmailing her sister the same way I did with her. Park Ah-young, on the other hand, thinks her sister has suddenly lost it.

"Y-you go first... and I'm fine doing it together too... so don't leave me out, okay?"

"...Unni, did you take some kind ‍‍‌‌⁠⁠‌‍‍‌⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠‌‌‌‍‌‌‌⁠‍‌‍⁠‌‌⁠⁠of drug?"

"Ah, what are you even saying... why drugs all of a sudden? Just go first, okay? I'm really fine. Seriously!"

"......"

Park Eun-ji's sharp glare lands on me. The look clearly asks what the hell I did to her sister.

"Ah... Noona, there's something you're misunderstanding."

At my words, Park Ah-young whips her head around.

"M-me? What misunderstanding? What do you mean?"

"I'm not dating Park Eun-ji."

"You fucking bastard, don't say that bullshit!!"

"See? She flips out even when I deny it."

"Th-then are you dating?"

Park Ah-young's eyes widen as she looks at Park Eun-ji. Park Eun-ji mutters with a sour expression.
